Scientists have found evidence that the Asian continent was free of permafrost all the way to its northerly coast with the ...

The Arctic tundra is now emitting more carbon dioxide than it absorbs, according to the latest Arctic Report Card released by ...

The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.; Wildfires and permafrost thaw ...

For millennia, the tundra regions of the Arctic drew in carbon from the atmosphere and locked it in permafrost. That is the case no more, according to an annual report issued on Tuesday by the ...

Here are some key takeaways from this year's Arctic Report Card: Arctic tundra: carbon sink to carbon source. Permafrost is full of carbon that has been locked away by plants over millennia.

The Arctic permafrost region as a whole — which encompasses tundra and forests — has become carbon neutral over the past 20 years, meaning it’s neither absorbing nor releasing excess CO2 ...

As permafrost — Arctic soil that typically remains frozen year-round — begins to thaw, ancient plant matter that was packed into that ground begins to decompose, releasing methane and carbon ...

Tuktoyaktuk itself now stands face to face with the Arctic Ocean’s increasingly angry Beaufort Sea, and rests atop 1,300 feet to 1,600 feet of thawing permafrost threatening to sink it.

But warming air temperatures in the Arctic are breaking down permafrost across the tundra, in some cases, severely. The Arctic report, for example, showed Alaskan permafrost temperatures in 2024 ...
